This advanced unilateral exercise develops elite-level pulling strength and core stability by using a band to assist the transition toward a full single-arm pull-up. It heavily recruits the lats and obliques to manage the intense rotational forces and vertical load.

Setup
- Loop a resistance band over the pull-up bar or the top crossmember of a power rack.
- Grip the bar with your working hand using a strong overhand or neutral grip.
- Grip the resistance band with your non-working hand at chest or shoulder height to provide assistance.
- Assume a dead hang position with your working arm fully extended and your core braced to prevent rotation.
How to do it
- Exhale and initiate the pull by depressing your shoulder blade and driving your elbow down toward your ribs.
- Pull your chin toward the bar while using the band-assisted hand only as much as needed for balance and upward force.
- Inhale as you lower yourself back to a full hang with a controlled 3-second tempo.
- Complete all reps on one side before switching to the other to ensure equal volume.
Form checklist
- Keep the working shoulder packed down and away from your ear throughout the movement.
- Engage your obliques and core to prevent your body from rotating or spinning under the bar.
- Maintain a vertical path; avoid swinging your legs or using momentum to reach the top.
- Ensure the working arm reaches full extension at the bottom of every rep.
Pro tips
- The lower you grip the band with your non-working hand, the less assistance you receive; use this to micro-load your progress toward an unassisted rep.
- Squeeze the bar as hard as possible with your working hand to increase neural drive and improve shoulder joint stability.
Make it harder
- Switch to a thinner resistance band to reduce the level of mechanical assistance.
- Incorporate a 2-second isometric hold at the top of the movement with your chin over the bar to build peak contraction strength.
Frequently asked
- What muscles does the resistance band assisted single arm pull up work?
- The resistance band assisted single arm pull up primarily targets the lats and trapezius, and also works the abs and serratus anterior as secondary muscles.
- What equipment do you need for the resistance band assisted single arm pull up?
- The resistance band assisted single arm pull up uses resistance band.
- Is the resistance band assisted single arm pull up good for beginners?
- The resistance band assisted single arm pull up is rated advanced. Build a base with simpler variations first, then progress to it with light load and strict form.
